Former Apple Genius Bar member gives you tips on how to extend battery life on your iPhone and iPad

The ex-Apple Genius Bar employee says to disable location and background app refresh for Facebook. Doing so on his new Apple iPhone 5s increased battery life by 12% to 17%. In a similar vein, disable background app refresh for apps that you don't care about. This seems to make perfect sense, right? Also, stop closing apps when you are through with them. Closing these apps removes them from RAM, which means that when you open the app again, it will have to re-load into memory which will eat away at battery life.
Loveless suggests temporarily stopping email notifications. He says that sometimes this feature alone is the cause of battery issues on an iOS device. You can lengthen the time that the phone waits to fetch your email, which might improve battery life. And he has seen times where an iOS device goes into an endless loop, looking for mail constantly. This will kill an iPhone battery 6 hours after you remove the charger. With this problem, you will see Standby and Usage times in Settings > General > Usage, exactly the same because of a problem with push email.
Push notifications by themselves only wake your phone for five to ten seconds. But if you have 50 of them in a day, it can add up. So Loveless says to disable push notifications for apps that annoy you. He also suggests that you turn off battery percentage readings. He says that people are so nervous about battery life that they are constantly checking how much life is left on their power source. But if you keep checking the battery life percentage reading, that move alone can also lead to a lower battery life. If you were to check the percentage of battery life remaining twice as much as before you added the percentage numbers, you are cutting the battery life in half, according to Scotty. He also recommends that iPhone and iPad owners make a Genius Bar appointment so that they can get their device run through the new 'Extended Battery Life Test' that allows for an detailed report of their battery usage. If the report shows a defective battery, and the device is under warranty, the battery can be changed immediately for free.
If you own an Apple iPhone or Apple iPad, why not give these tips a chance. You have nothing to lose, and the life you save just might be the one belonging to your battery.
